To all whom it may concern:-

Be it known that I, ANTHONY Fmokmz,

Fig. 6 is a section taken on the line 6-6 of Fig. 1.

.a citizen of the United States, and resident In general the device comprises a supply of Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Bituminous Distributors, of which the following is a descriptlon, reference being had to the accompanying drawings, which are a part of this specification.

The invention relates to distributors of bituminous material and petroleumproducts for road-making and more particularly to the system employed in conducting the mar5 terial to and from the storage or supply tank.

The material which this manhine, is designed to handle naturally solidifies and congeals under ordinary temperatures and the object of the invention is to provlde an efficient circulating system in which the material is conducted from the tank to the discharge manifold and part or all of which is returned to the tank through direct connections cutting down heat losses and one in which the pressure of the material passing through the distributing manifold is regulated by a valve which is self draining and non-clogging.

It sometimes happens in machines of this kind that the circulating .pump becomes! clogged and has to be heated by torches and in fact for eflicient circulation the pump should be kept heated and as machines of as this kind are carried on an automobile truck I have found that a simple andeffective way of guarding against clogging of the pump and of keeping it heated is to conduct the hot exhaust gases from the engine around at the pump and so far as I am aware this particular feature is broadly new and is a great improvement over former constructions.

The invention further consists in' the several features hereinafter set forth.

In the drawings: Fig. 1 is a vertical sectional view through the machine taken on the line 1--1 of Fig.- 2;

Fig. 2 is a section taken on the line 2-2 of Fig. 1

Fig.3 is a section taken on the line 3-3 of F 1g. 1; t

Fig. 4 is a section taken on the line 4- 1 of Fig. 3;

Fig. 5 is an enlarged vertical sectional 55 View of the pressure regulating valve;

tank 7 for the heated material, a discharge manifold 8, means for circulating the heated material through the manifold, means for regulating or controlling this circulation, means for discharging the material from the manifold and other features hereafter described.

The tank 7 is mounted upon an automobile or other vehicle 9 and the material is delivered from the tank to a pipe 10 and thence by a pump 11 and pipe 12 to the central portion of the manifold 8. From the manifold 8, some or all of the material is returned to the tank through pipes 13 and 1 1 leading from the ends of the manifold to a return p1pe 15 leading to a valve fitting 16 in the bottom of the tank 7; The pump II delivers the material to the manifold under pressure. The pipe 10 is vertically disposed and the pipe 12 inclined downwardly so as to drain the material into the manifold when the supply is shut off as hereinafter described and the vertically disposed pipe 15 and the downwardly incllned pipes 13 and 14 drain the material into the manifold when the return valve is shut off. Thus the mamfold being at a lower level than the other pipes and the other pipes being inclined to drain into it when the supply is shut off the material in the pipes will drain into the manifold and from thence it is discharged by the discharge mechanism hereafter described so that the whole system is-kept clean and free from deposits of congealed material. Also with this construction the heated material from the tank is delivered under pressure to the intermediate portion of the manifold, passes therethrough to the ends and returns through the pipes 13, 1 1, and 15 to the tank thus continuously circulating the heated maplerial through the manifold and keeping it The rate of flow of material from the tank 7 to the pipe '10 and the shutting 0d of supply of material to this pipe and the pump 11 is controlled by valve 17 adapted to register with its seat 18 in a coupling 19 securing the pipe 10 to the bottom of the tank 7. The movement of this valve is controlled through a rod 20, lever 21, link 22, and lever 23 which linkage is adapted to be held in different positions of adjustment by means of 110 20 the ports 31 and thus prevent clogging of i 31, interior 29 and ports 30 to the tank'and when the valve is closed the material Wlll a spring pressed pawl 24 on the lever 23 engaging a segmental toothed rack 25 on the outside of the tank. The downward movement of the lever 23 will through the linkage just described raise the valve 17 and the upward movement of said lever will lower the valve 17.

- To increase or decrease the pressure of the material within the manifold I provide av valve in the return to the tank 7. This valve consists of a piston valve member 26 seated in a bore 27 in the fitting 16 said valve having a hollow interior 29, laterally disposed ports 30 leading into said interior and ports 31 leading from the interior to the pipe 15. ()n the raising of the valve the material from the pipe 15 passes through the ports flow down or drain out of the valve through the valve. Thevalve ma be ralsed and lowered through an suita le means as the rod'32 working in t e guide 33 and extending up throu -h the tank and connected to a lever 34 which in turn is connected by a link 35 with a lever 36, the valve being normally closed by a spring 37 acting against the rod 32 and being maintained in different adjusted positions by means of a spring pressed pawl 38 engaging a segmental toothed rack 39. The member 26 never moves wholly out of the bore 27 but only far enough to move the ports 30 above the valve seat and this keeps the valve in line and insures its proper operation. 7

For convenience in filling the supply tank 7 I have provided a valve member 40 in the fitting 41 which connects the pipe 12 to the outlet end 12 of the pump 11 and also connects the filling ipe 42 to the outlet end 12' of said pump. his valve member has two spaced apart port openings 43 and 44 adapted to register with the pipes 12 and 12 respectively when the pump is delivering material to the manifold or to register with the pipes 12 and 42 when the drive of the part of the manifold and connected by a bell crank lever 48 to a rod 49. The tapering of the sides, of the manifold provides for eflicient drainage when the valves are open.

In the drawings I show rods 49 on either side of the machine to which seriesof valves are connected through the leversv 48 and each of these rods 49 s reciprocated to open and close its respective walves by means of a From the foregoing description it will be noted that provision is made for filling the tank direct from the source of supply through the pump, that while the machine is running there is a constant circulation of material through the manifold, that the outlet valve from the tank regulates the amount of material fed to thepump and the return valve regulates the pressure of the material in the manifold, that the pipingfrom and to the tank is so arranged as to drain to the manifold when the tank is shut off, thereby preventing clogging of the circulating system and the material drained from the ipes may be readily drained from the mamfold and that the general design and combination ofthe parts produces an eflicient circulating system and one which will efficiently take care of material having a natural tendency to clog the system. It will also be noted that both the valves for controlling the passage of material from and to the tank 7 are located within the tank and thus ke t heated by the hot material within the tan While I have illustrated and described one specific embodiment of my invention I desire it to be understood that constructions coming within the scope of. the appended claim deem to be within the spirit of my invention.

. What I claim as my invention is:

In a bituminous distributor, the combination, with a motor driven vehicle and a supply tank and discharge manifold carried thereby, of means including a pump for de livering material from the tank to the manifold under pressure, an open bottom container surrounding the pump and spaced from the same, and a pipe for conducting the exhaust gases from the motor into said container to heat said pump and exhaust the gases to the atmosphere.

In testimony whereof, I- aflix my signature.
